The \h{Gehman Dendrite with Ski} $G_s$ is a \g{dendroid}
formed from the \g{Gehman Dendrite} $G$ and the
\g{Cantor Ternary Set} $C$ with a formula
$$
G_s = \{(x,y,z)\in R^3 : (x,y)\in G \} \cup
\{(x,y,z)\in R^3 : x\in C, y=0, |z|\le 1 \} \quad .
$$

In fact we attach uncountably many segments of length 2 with
their midpoints to the points of \g{Cantor Ternary Set} (the
\g{end point}s of \g{Gehman Dendrite}). See \cite[p. 16]{jjc1995}.
